Abstract (en)
[origin: WO9425902A1] A film cleaning apparatus has a container (32) in which a film (22) is exposed to mercury. This may be achieved by immersing the film in a mercury bath (34), exposing the film to mercury pressure jets (44, 46) or a combination of both. The mercury effects removal of contamination such as dust particles and grease from the surface of the film.
